If mArc BC is 105°, what is mArc CD? (3 points)

Mathematics

Virty [35]2 years ago

Well, its a given more or less when referred to the measure of an Arc, it's usually meant the CENTRAL ANGLE made by that arc in this case, 148 is the CENTRAL ANGLE, so if BCD is 148 and BC is 105, then CD is the rest of the 148. 148 for the central angle, if we use up 105 for BC, how much is left over for CD?

Line bc is represented by 3x + 2y =8 line ad is a represented by -3 x -2y =6 what is the relationship of line bc to line ad expl
Vlad1618 [11]

Answer:

Parallel lines

Step-by-step explanation:

Line BC:

3x + 2y =8

Line AD:

-3x - 2y =6

Adding both equations, in this case, gives us the point at which the lines intersect:

3x + 2y-3x-2y =8+6\\0=14

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.

Given 3 sides of a triangle - how to tell it right, acute, or obtuse 8,11, 16
user100 [1]
Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.

Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2  Which means triangle is obtuse triangle.

Answer: Obtuse Triangle
